 - Since 5 is positive, the inequality direction remains the same.

Inequality at the end of Step 1:

 - We turn the fraction into parenthesis by multiplying because a fraction is originally is dividing, so we have to do the opposite, which in this case is multiplying.  

Inequality at the end of Step 2:

 - We do this to get 1 number/variable on each side.

Inequality at the end of Step 3:

 - Since −6 is negative, the inequality direction is changed.

Inequality at the end of Step 3:

 - Extracting and cancelling out just means dividing. So we just divide the numerator and denominator by -2.

Inequality at the end of Step 5:

 - You can figure this out by dividing 65 by 3 which gives you a decimal, then turn the decimal into a fraction.

Answer:

$63

Step-by-step explanation:

First, divide 28 by 4 to get 7

Now we know that one ticket cost $7.

Do 7 times 9 to get 63

9 tickets costs $63

9 movie tickets would cost $63.

Since 4 movie tickets cost $28, you can divide 28 by 4 to get 7. From here, you can multiply 7 by 9 to get 63.

May I have brainliest please? :)

Step-by-step explanation:

First, convert 2,300 ounces into pounds.

2,300oz. - 143.75 pounds

You then need to add the pounds from the pilot and Tristan's.

143.75 + 200 = 343.75

If the hot air balloon can hold 350lbs, then both Tristan and the pilot can ride it together. The reason why they can ride it together is because 343.75 pounds is less than what the hot air balloon can originally hold, which is 350lbs.

Answer:

They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.

the sugar is sold at rupees 5.4 per kg at a loss of 10% at what price should it be sold per kg to earn a profit of 20%

Answer:

7.2 rupees

Step-by-step explanation:

Given that at a loss of 10 percent which is 90% price, we have sugar sold at 5.4 rupees per k.g

Hence, at 100 percent we have => 5.4 × (100 ÷ 90 )= 6 rupees per kg.

Therefore, at 100 percent, where we have 6 rupees per kg, to make a profit of 20% we have

6 rupees per kg x 120% = 6 × 1.2 = 7.2 rupees per kg.

Hence, the final answer is 7.2 rupees per kg to make a profit of 20%.

Answer:

y = 5x - 3

Step-by-step explanation:

The Slope of a Line

Suppose it's given a line that passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The equation of the line in slope-intercept form is:

y=mx+b

Where:

m = slope  

b  = y-intercept.

We are given the points (-1,-8) and (3,12). Compute the slope:

[tex]\displaystyle m=\frac{12+8}{3+1}=\frac{20}{4}=5[/tex]

The equation of the line now has one known value:

y = 5x + b

Let's use the point (3,12) to find the value of b:

12  = 5(3) + b = 15 + b

Solving for b:

b = 12 - 15 = -3

The required equation of the line is:

y = 5x - 3

Answer:

84

Step-by-step explanation: (edited)

52% problems are pointless i.e. 48% are NOT pointless.

Recall that 1% = 1/100.

Therefore 48% = 48/100 = 12/25.

Let x be the number of problems that are not pointless.

x/175 = 12/25

x = 84

Answer:

Answer:

The answer to the question provided is 30.

Step-by-step explanation:

[tex] \frac{18}{27} = \frac{20}{x} \\ \\ \frac{540}{18} = \frac{18x}{18} \\ \\30 = x[/tex]

Happy to help!

=====================================================

Explanation:

Due to the parallel lines, we have two similar triangles. So the sides are proportional.

18/27 = 20/x

2/3 = 20/x

2x = 3*20

2x = 60 .... cross multiply

x = 60/2

x = 30

---------------

Another way you can approach it is to say

18/(18+27) = 20/(20+x)

18/45 = 20/(20+x)

2/5 = 20/(20+x)

2(20+x) = 5*20

40+2x = 100

2x = 100-40

2x = 60

x = 60/2

x = 30

Answer:

D.

Step-by-step explanation:

[tex]\frac{9}{16}[/tex] converted to decimal is 0.5626

[tex]\frac{7}{12}[/tex] converted to decimal is 0.5833

So answer choice D is the correct answer.

Answer:

8.142

Step-by-step explanation:

Answer: You can decide to choose any of these but they're all the same!

8 R 1

Decimal form:

8.1 (if you round it to the nearest tenths).

8.14 (if you round it to the nearest hundredths).

8.143 (if you round it to the nearest thousandths).

Step-by-step explanation:

When you begin the division, you have to think of what is the highest number that is less than 57 that is a multiple of 7, that number is 56. 56/7 is 8 which is where I got the 8.

57 - 56 = 1 which is the remainder.

If you want to write it in decimal form, you divide the 1 by 7 and since you'll get a decimal number with 0.14.. you had that number to 8, which gives you your answer in decimal form!

Hope that helped!

Answer:

[tex]A=1347.7\ cm^2[/tex]

Step-by-step explanation:

Given that,

Radius of a cone, r = 13 cm

Slant height of the cone, l = 20 cm

We need to find the surface area of the cone. The formula for the surface area of the cone is given by :

[tex]A=\pi rl +\pi r^2[/tex]

Put all the values,

[tex]A=\pi r(l + r)\\\\A=\pi \times 13(20 + 13)\\\\A=1347.7\ cm^2[/tex]

So, the surface area of the cone is [tex]1347.7\ cm^2[/tex].

Answer:

Zeros → (-2, 0) and (4, 0)

Step-by-step explanation:

Equation of the graph has been given as,

y = [tex]\frac{1}{2}x^{2} -x-4[/tex]

For zeros of the function,

y = 0

Therefore, [tex]\frac{1}{2}x^{2} -x-4=0[/tex]

By solving the equation algebraically,

x² - 2x - 8 = 0

x² - 4x + 2x - 8 = 0

x(x - 4) + 2(x - 4) = 0

(x + 2)(x - 4) = 0

x = -2, 4

Therefore, coordinates of the zeros will be (-2, 0) and (4, 0).

Let's confirm the zeros (x-intercepts) from the graph attached,

Coordinates of the x-intercepts are,

(-2, 0) and (4, 0)

Answer:

I think it's 15 Quarters.

Step-by-step explanation:

The required number of dimes and quarter Whitney has is 11 and 9 respectively.

Given that,
Whitney has 20 coins in her purse. Some are quarters and some are dimes. The total value of the coins is $3.35. The number of quarters Whitney have is to be determined.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Let the number of dimes be x and the number of quarters be y,
According to ot the question,
x + y = 20
x = 20 - y - - - - (1)
and
0.1x + 0.25y = 3.35
From equation 1
0.1[20 - y] + 0.25y = 3.35
y = 9
Now,
x = 20 - 9
x = 11

Thus, the required number of dimes and quarters Whitney has is 11 and 9 respectively.
